themostconvenient'fortheinsertingopera:

during-the time in 'WlllCll itisjbeingQin- 0 I accomplish these objects by providing a grid having a cement applying surface adapted to coatthe bottom surface of the lining with cement to a suflicient extent to cause the necessary adhesion when laid thereon and which is arranged to support the middle portion longitudinally. at a higher elevation than the side portions, so that the side portions of the lining may be pinched together end the lining lifted from the grid in position for ready insertion in a shoe. r

For a more complete understanding of my invention reference is made to the ac companying drawingin which Fig. 1 is a plan view showing a preferred embodiment of my invention.

Fig. 2 is a transverse sectional view thereof on a larger scale.

Figs. 3 and l are detail views illustrating the method of removing the lining from the cementing grid. 7

Figs. 5 and 6 are sectional views illustrating the manner of inserting the lining after removal'from the grid and Figs. 7 and 8 are plan end end views illus trating a modified embodiment of my inventlon.

According to my invention, I provide a grid frame which comprises side rods a which are supported in end bars b at each end, said end bars being attached to verti cally' disposed lifting rods 0 which are adapted and arranged to be moved vertically bya treadle or other suitable means not shown, so that theigridmay be raised and lowered in a liquid cement containing pan orljtray (Z, from a'position in which it is completely submerged" to a position in which its upper sideis above the liquid level; A series of bars 6, consisting of strips of fiat metal are arranged edgewise, or in vertical planes and in parallel relation on saidrods a, which pass through the opposite end portions of said bars, and on which said bars are held in spaced relation by means of'interposed washers 7", said bars and washers being clamped together by nuts on the ends of the rods a, ma well known manner. The upper edges of said bars are finished to form cement ca'rrying'faces arranged in' alignment transversely and are convexly curved longitudinally on the same radius,

' so that they lie in acylindrical surface having a horizontal axis and form' a transversely convex cementing surface. The grid is of oblong form, the length which corre sponds to'the combined thickness of the bars and interposed washers, being substantially greater than the width, which corresponds to the length of the bars,'so that the cement applying surface of the grid is transversely convex and longitudinally horizontal, the

highest points on said surface being in the The operator then,'while the grid is thus held, lays a sole shaped sock lining, as a,

on the surface formed by said edges in longitudinal position, so that a longitudinal element of said surface will approximately coincide with the middle longitudinal line of the lining, as indicated in Fig. 1. As the linings are usually made of very thin flexible leather, it will conform by its own weight to the cementing surface, so that, as

soon as the lining is placedv thereon, a series of transverse stripes of cement will be applied to the under surface of the. lining throughout its length which will extend from one side-edge to the other. It will be observed that when the lining is laid on the grid in this manner, its middle portion will be held above its side portions, so thatit will be partly folded longitudinally, as indicated in Figs. 2 and 3.

The operator then places the thumb and forefinger of each hand on the wider portion of the heel and forepart of the lining, as indicated in Fig. 8, and then, while press ing firmly downward, moves the thumb and finger of each hand toward each other, so as to bring the opposite sideportions of the lining together, as indicated in Fig. 4, thus folding the lining longitudinally throughout its entire length andbringing the oppo-' site portions of the cemented surface to gether.- As thus held, but little or none of the cemented surface will be exposed, so that the operator may then'insert the lining in the shoe while held in this position, and without changing the position of her hands thereon, in the manner indicated in Fig. 5. The lining usually has enough inherent stiffness, when held in this manner, to prevent it from bending down at points at which it is not supported, so that itmay be readily inserted in the shoe. 7 hen it has been fully inserted, it will be spread out flat on the shoe bottom, so that it will adhere thereto. In this way the lining may be readily inserted without having the cemented surface come in contact with the lining of the shoe upper. By providing a form of grid which performs a preliminary folding of thelining at the same time that it cements it, the operator is able to finish the folding operation and without contact of the fingers with the cement carryingsurface of the grid, this latter factbeing a matter of great innp'ortance, when t'1'1e--o'p, rat ion i repeatedly pet-- formed'f 1 While the operator -.mayj ordinarily place the lining. on the middle' 'portion of the g rid,"

as showniin Fig.1, this -is not essential, pro-' vided it is placed thereon in longitudinal relation, audit is easily, possible for two operators to work on one machinefi-at'the same time by working at oppositeflsides'of the grid, and placing .the linings thereonat each side of its middle: line, the curvature of the *cementvapplyingfedge of each bar "being described. 1

In this form the manner of supporting the grid bars 9 thereof is the same as that already described, but the bars are bent in zig-zag formation, so that the extreme lateral positions at one side of one bar will be opposite the extreme lateral position of the corresponding adjacent points at the adjacent side of the next bar. The edges at the opposite side ofthe transverse middle'line of each bar is formed to slope downward in an inclined plane fromjthis point, as

shown in Fig. 8, so that the cementing surface which is formed by the upper edges of the bars lies in two planes which meet in the middle longitudinal line of the grid.

The manner of using this form of grid is practically identical to that already de scribed, with the exception that care must be taken so to place the lining thereon that its middle line approximately coincides with the vertex of the angle or the line of intersection of the planes in which the cementing surfaces lie. While with this form of my invention, the operation of preliminary partial folding will be more effectively performed by the grid than it will be with the convex construction already described, so that the lining may be folded more easily and accurately, as it is a prerequisite that.

the lining be placed accurately in position on the grid, it has been found that the operator cannot do the work as rapidly as with the convex form of grid as time is lost in placing it in position. Also,except where extremely thin linings are being cemented, it is necessary to draw the fingers along the length of the lining and press it down firmly on the grid to insure contact with the bars at all points, and this causes further delay, and with the convex grid, all portions of the lining will be cemented by placingit in position thereon, The zig-zag construction is advantageous when it is especially desired to sp reatl t-hecement over practioall'yiheen I the surface and-not have "it appliedin stripes; as the movementof the opposite p'ortions of the liningo'n thejgr-id surface-trans vers'ely," or longitudinally of fithezbars will cause aunovementobliquely to ther portions-j of the bars engagedl Itwill be obvious that the zi'g-zag constructionm'ay be 'applied with-k equal advantage to the barshavin'g the eon-'- vexedgesh'own 'in'Flglf 2', but 'an objeetlon tothis construction is=that it increases "the frictional en a ementontheliningwhen thew OPPOSllIQ sides of the 'latter are pinched to 4 gether while pressed onto the grid. That is, the straight bars offer muclrless resistance to the action of sliding the oppositefportio'ns together on the grid, than the zigzag conf I struction. V
